Version number, Splash screen, Auto-update

[jim sims]

If I make an OS X standalone I can check the version number in the  
Finder using 'Get Info'.

If I use a splash-screen, auto-update technique to update my app then  
I can change the version number that my own About menu shows. But that  
change is not reflected in the Finder 'Get Info'.

So, if the user checks a version number in the Finder they might think  
they have the wrong version.

The only resolution I can think of is to use something like: version  
1.0 (123) in the About menu, where the parentheses indicate the  
changes in versions. The user, if they check the About to be sure of  
what the Finder shows, might be satisfied but I suspect few users will  
do so.

How do others handle this?
